2015-05-19tcp: only undo on partial ACKs in CA_LossYuchung Cheng1-3/+6
Undo based on TCP timestamps should only happen on ACKs that advance SND_UNA, according to the Eifel algorithm in RFC 3522: Section 3.2: (4) If the value of the Timestamp Echo Reply field of the acceptable ACK's Timestamps option is smaller than the value of RetransmitTS, then proceed to step (5), Section Terminology: We use the term 'acceptable ACK' as defined in [RFC793]. That is an ACK that acknowledges previously unacknowledged data. This is because upon receiving an out-of-order packet, the receiver returns the last timestamp that advances RCV_NXT, not the current timestamp of the packet in the DUPACK. Without checking the flag, the DUPACK will cause tcp_packet_delayed() to return true and tcp_try_undo_loss() will revert cwnd reduction. Note that we check the condition in CA_Recovery already by only calling tcp_try_undo_partial() if FLAG_SND_UNA_ADVANCED is set or tcp_try_undo_recovery() if snd_una crosses high_seq.

2015-05-19net/ipv6/udp: Fix ipv6 multicast socket filter regressionHenning Rogge1-1/+3
Commit <5cf3d46192fc> ("udp: Simplify__udp*_lib_mcast_deliver") simplified the filter for incoming IPv6 multicast but removed the check of the local socket address and the UDP destination address. This patch restores the filter to prevent sockets bound to a IPv6 multicast IP to receive other UDP traffic link unicast.

2015-05-19xen/events: don't bind non-percpu VIRQs with percpu chipDavid Vrabel3-6/+10
A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different VCPU than it is bound to. This can result in a race between handle_percpu_irq() and removing the action in __free_irq() because handle_percpu_irq() does not take desc->lock. The interrupt handler sees a NULL action and oopses. Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER). # cat /proc/interrupts | grep virq 40: 87246 0 xen-percpu-virq timer0 44: 0 0 xen-percpu-virq debug0 47: 0 20995 xen-percpu-virq timer1 51: 0 0 xen-percpu-virq debug1 69: 0 0 xen-dyn-virq xen-pcpu 74: 0 0 xen-dyn-virq mce 75: 29 0 xen-dyn-virq hvc_console Signed-off-by: David Vrabel <david.vrabel@citrix.com> Cc: <stable@vger.kernel.org>

2015-05-19pwm: img: Impose upper and lower timebase steps valueNaidu Tellapati1-12/+64
The PWM hardware on Pistachio platform has a maximum timebase steps value to 255. To fix it, let's introduce a compatible-specific data structure to contain the SoC-specific details and use it to specify a maximum timebase. Also, let's limit the minimum timebase to 16 steps, to allow a sane range of duty cycle steps.

The index for the hardware layer is always >=0. Previous code that also used -1 as special index is now gone. Also apply this to 'ch_enabled' (decon/fimd), since the variable is on the same line (and is again always unsigned).

2015-05-19drm/exynos: mixer: don't dump registers under spinlockTobias Jakobi1-4/+4
mixer_regs_dump() was called in mixer_run(), which was called under the register spinlock in mixer_graph_buffer() and vp_video_buffer(). This would trigger a sysmmu pagefault with drm.debug=0xff because of the large delay caused by the register dumping. To keep consistency also move register dumping out of mixer_stop(), which is the counterpart to mixer_run().

Move the defines for the pixelformats that the mixer supports out of mixer_graph_buffer() to the top of the source. Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on the plane's pf (and not bpp). Also add handling of RGB565 and XRGB1555 to the switch statement and exit early if the plane has an unsupported pf. Partially based on 'drm/exynos: enable/disable blend based on pixel format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>. v2: Use the shorter MXR_FORMAT as prefix. v3: Re-add ARGB8888 because of compatibility reasons (suggested by Joonyoung Shim).

2015-05-19drm/exynos: plane: honor buffer offset for dma_addrTobias Jakobi1-1/+1
Previously we were ignoring the buffer offsets that are passed through the addfb2 ioctl. This didn't cause any major issues, since for uni-planar formats (like XRGB8888) userspace would most of the time just use offsets[0]=0. However with NV12 offsets[1] is very likely non-zero. So properly apply the offsets to our dma addresses.

2015-05-19drm/exynos: fb: use drm_format_num_planes to get buffer countTobias Jakobi1-38/+1
The previous code had some special case handling for the buffer count in exynos_drm_format_num_buffers(). This code was incorrect though, since this special case doesn't exist for DRM. It stemmed from the existence of the special NV12M V4L2 format. NV12 is a bi-planar format (separate planes for luma and chroma) and V4L2 differentiates between a NV12 buffer where luma and chroma is contiguous in memory (so no data between luma/chroma), and a NV12 buffer where luma and chroma have two explicit memory locations (which is then called NV12M). This distinction doesn't exist for DRM. A bi-planar format always explicitly comes with the information about its two planes (even if these planes should be contiguous).

2015-05-19ALSA: pcm: Modify double acknowledged interrupts check conditionKoro Chen1-1/+1
Currently in snd_pcm_update_hw_ptr0 during interrupt, we consider there were double acknowledged interrupts when: 1. HW reported pointer is smaller than expected, and 2. Time from last update time (hdelta) is over half a buffer time. However, when HW reported pointer is only a few bytes smaller than expected, and when hdelta is just a little larger than half a buffer time (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged. The condition #2 uses jiffies, but jiffies is not high resolution since it is integer. We should consider jiffies inaccuracy.

2015-05-18sched: always use blk_schedule_flush_plug in io_schedule_outShaohua Li1-4/+1
block plug callback could sleep, so we introduce a parameter 'from_schedule' and corresponding drivers can use it to destinguish a schedule plug flush or a plug finish. Unfortunately io_schedule_out still uses blk_flush_plug(). This causes below output (Note, I added a might_sleep() in raid1_unplug to make it trigger faster, but the whole thing doesn't matter if I add might_sleep). In raid1/10, this can cause deadlock. This patch makes io_schedule_out always uses blk_schedule_flush_plug. This should only impact drivers (as far as I know, raid 1/10) which are sensitive to the 'from_schedule' parameter.

By inspection, this appears to be a typo. The gating comparison involves vxlan->dev rather than dev.

2015-05-18watchdog: Fix merge 'conflict'Peter Zijlstra1-5/+15
Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf665a62 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d293233 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again.
